I've just skimread most of this thread, but I just wanted to chip something in.
A lot of people think that TVNZ is government funded. Apart from things like contestable NZ On Air funding for some programs and funding of transmitting programmes to the pacific, TVNZ is not government funded. In fact, the money flows in the opposite direction. The government, as the sole shareholder, can take whatever dividend it wants. For FY2016, TVNZ earned a $12.7m profit. It paid $13.4m to the govt as a dividend. Total revenue was $326.1 million (down $23.9m), operating costs $303.3m (down about $10m on the previous year. Programme rights were about $46m.
Think about those numbers. TVNZ did not get to keep its profit and in fact had to fork over a little extra. It's an expensive business and there's not really much money to splash out on great programming. At the same time, people are finding new avenues for entertainment and the advertisers are moving away from tv advertising. All these factors influence each other and create a downward spiral. Think about that next time you wonder why free-to-air television is (poo emoji)
In case someone thinks I'm being anti-government, I don't believe a change in govt would necessarily improve prospects for TVNZ. A lot of the problems would still remain and I don't think any govt would be willing to throw in the amount of money required to Make TVNZ Great Again (sorry). Those numbers, I think, are quite sobering.
